Key Findings, Inspector's Opinions and Reasons for Judgements Made

No regulatory issues were raised during the inspection. A number of observations were shared during the hot de-briefs. These provide learning opportunities for EDFE and Radsafe (i.e. an organisation that provides the initial response to an incident on behalf of the consignor) to consider.

During the hot de-brief ONR fed back to EDFE and Radsafe that they considered the exercise had been challenging for the participants but it had been handled well. The CESC controller had managed the team and an effective response had been demonstrated. ONR had observed good examples of questioning attitude and responding effectively to uncertainty.

ONR agreed with all the opportunities to improve identified by EDFE during the exercise. However, the following points for consideration were emphasised by ONR:

These points for consideration were well received by EDFE and ONR thanked the participants for their efforts. EDFE’s internal regulator agreed to follow up on the areas raised by ONR during the feedback.

Conclusion of Intervention

The test of the offsite transport (Radsafe) exercise (Exercise Kilmarnock) met the declared objectives. Therefore, the test demonstrated compliance with the requirement of Schedule 2(4)(3) of the Carriage of Dangerous Goods (CDG) and Use of Transportable Pressure Equipment Regulations 2009 (as amended 2011). A number of learning points were identified by the duty holder and ONR. These were communicated and will be addressed as part of EDFE’s routine learning process. ONR will monitor the response to these findings as part of routine interaction with the internal regulator.

The intervention was rated GREEN.
